CysTRAQ - A combination of iTRAQ and enrichment of cysteinyl peptides for uncovering and quantifying hidden proteomes

► iTRAQ is compatible with cysteinyl peptide enrichment. ► Our protocol - CysTRAQ - is fast and ensures excellent peptide recovery. ► CysTRAQ increases proteome coverage. ► Both cysteinyl as well as non-cysteinyl peptide fractions can be analyzed and quantified.
